Available in four sizes (10.5mm to 15mm) with two collar angular settings (20 and 35 degrees). Features a circumferential collar for cortical arc loading and proximal compressive load distribution. Offered with or without a sintered beaded surface; non-sintered versions include a distal hole for a cement centralizer. Non-porous coated version is for cemented use only; porous sintered beaded version is for cemented or non-cemented press-fit use. Implanted by surgeons in clinical settings to replace the femoral head/neck, restoring joint function and reducing pain in patients with degenerative or traumatic arthritis. ## Clinical Evidence No clinical data provided; substantial equivalence is based on design, material, and geometric comparison to legally marketed predicate devices. ## Technological Characteristics Material: Cobalt chromium alloy (ASTM F-75). Design: Femoral hip component, 10.5mm-15mm sizes. Features: Circumferential collar, 5.708-degree trunnion taper, optional sintered beaded surface. Cemented or press-fit application depending on surface coating. ## Regulatory Identification A hip joint metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace a hip joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and an acetabular resurfacing component made of ultra-high molecular weight polyethylene and is limited to those prostheses intended for use with bone cement (§ 888.3027). ## Predicate Devices - DePuy AML Femoral Component ([K852198](/device/K852198.md)) - BioPro Horizon Femoral Component ([K962769](/device/K962769.md)) - Whiteside Biomechanics ([K961625](/device/K961625.md)) - StelKast Proform Cemented Femoral Component ([K951083](/device/K951083.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

The design is made available in four (4) sizes ranging from 10.5mm to 15mm. The stem portion of the femoral component is essentially identical to the DePuv AML Femoral Component (K852198) and the BioPro Horizon Femoral Component (K962769). The collar will be available in two different angular settings of 20 degrees to the horizontal and 35 degrees to the horizontal. The device will be offered with and without a sintered beaded surface, as depicted on the engineering drawings. The taper on the trunnion is a standard 5.708 degree angle as found on the Whiteside Biomechanics (K961625) and the StelKast Proform Cemented Femoral Component (K951083). The device has a circumfrential collar to load the bone on the cortical arc and distribute the compressive load of the implant as proximally as possible. The stems distal to the collar are essentially identical in geometry and size as the DePuy AML (K852198) and the BioPro Horizon (K962769). The non-sintered beaded surface device will have a 5mm hole in the distal tip of the implant to accommodate a cement centralizer from the StelKast Corporation (K951083). If further information is required please contact Dr. Louis Serafin, Signal Medical Corporation, 3315 Berry Drive, Lakeport, MI 48059, phone - 810-385-8302. This device is designed for cemented use only in the non-porous coated version. With the porous sintered beaded surface, the device is designed for both cemented and non-cemented press-fit use. This femoral component of the hip is indicated for use in patients with: 1 - Osteoarthritis - 2 Rheumatoid Arthritis - 3 Traumatic Arthritis and when the use of a more conservative procedure has failed or is unacceptable. -3- {1}------------------------------------------------ Food and Drug Administration 9200 Corporate Boulevard Rockville MD 20850 DEC - 4 1997 Louis A.
